Galaxy S21 Ultra, What was announced on Thursday, It comes with a photo sensor with the same resolution (resolution) as Samsung’s two previous flagship devices, but this weekend Published The company revealed the details of the new sensor that comes with the S21 Ultra and claimed that it presents photographic capabilities unprecedented in the cellular world.
ISOCELL HM3 is the third flagship sensor in the company’s series and, as mentioned, it still offers a maximum security of 108 megapixels, but includes some updates. Compared to its predecessor, Incorporated inGalaxy Note 20.
First, the sensor size and spot size returned from 1 / 1.52 inches and 0.7 microns, respectively, in the previous generation, to 1 / 1.33 inches and 0.8 microns, as in the first generation. , which means that each point absorbs more light. The dot matrix is still built as in the second generation, capable of converting any 9-point square into a single point with a huge 2.4 micron size, to further increase its light absorption for photography in challenging lighting conditions. This allows the sensor to capture 12 megapixel images in the dark with almost no noise or interference.
Another feature designed to primarily enhance shooting in the dark is Smart ISO Pro, which enables wide dynamic range by taking two images in different dynamic ranges simultaneously and then merging them into one image with 12-bit color depth, allowing for a Reproduction of nearly 69 billion colors, 64 times than 10-bit photography. This technology also allows you to capture more light during shorter exposures, so shooting in the dark includes less movement and smudging.
Samsung has solved the focus problem of the previous generation with the help of Super-PD Plus technology, which enables faster focusing using special lenses for the distance sensor, which improve metering by 50%.
The firing speeds of the new sensor are also very impressive: it is capable of capturing 10 images per second at its maximum resolution, which is equivalent to more than 12K in current video concepts; At 8K you can shoot at 30 frames per second; With a resolution of 12 megapixels, which is equivalent to a video quality between 4K and 6K, it can shoot up to 90 frames per second; And 4K up to 120 frames per second.
A final improvement, less dramatic but no less important, is the company’s claim that in preview mode, that is, until the shutter button is pressed, the sensor consumes about 6.5% less power. , which should guarantee more still photography time.
